We're pretty deep in a single thread here, but the original article isn't saying "don't use analytics", it's saying "don't use Google Analytics".
Your SaaS or webpage probably gathers 80% of what Google Analytics does in your log files. It could without doubt provide deeper insights that GA is capable of by adding your own behaviour tracking code (which can be written with the understanding of your specific problem dom ain, rather than be an "everything to everybody" generalised solution).
Nobody is suggesting we shouldn't collect usage and performance data, the thesis here is that we shouldn't send all that directly to the worlds most profitable advertising agency, just because they'll draw us some pretty graphs for free.
